A project to enhance drainage facilities on US 101 from two miles north of the US 101/State Route 154 Separation to just north of Union Valley Parkway is now underway.
Lane closures will occur 7 a.m.-7 p.m. Monday, May 12-Friday, May 16 to allow for the placement of protective barrier.
Most of the work will occur on the shoulders behind k-rail, but travelers will encounter intermittent lane closures during this project for the placement of protective barrier, Caltrans said.
The project will rehabilitate drainage systems at 11 locations by providing repairs and improvements to extend the service life of the existing culvert systems.
In addition, existing lighting systems will be replaced, and lighting will be added at three locations near Los Alamos. Transportation Management System replacements will include traffic loops and microwave radar sensor.
Contractor for the $3.3 million project is CCFG Construction from Sonora, California.
This project is expected to be complete in December.
